"Dynasty politics isn't an important issue now, country's problems are the main issue. Only because of dynasty politics and regional politics, this country developed in several states. We are not bothered about criticism from the BJP."

DMK Chief MK Stalin, who voted at a polling booth at SIET College in Teynampet, Chennai, alleged that the Election Commission is in connivance with Prime Minister Narendra Modi-led NDA government, adding that the Election Commission would be reformed if the Opposition is voted to power.

"This year election has been full of Rs 500, 1000, 2000 and 10,000 currency notes. All attempts have been made to buy votes but in spite all this I have full faith in voters of Tamil Nadu who will exercise their democratic rights fairly," said MK Stalin.

"Regarding the election issues, I can only request the Election Commission but unfortunately the Election Commission itself has become a party to the Modi-led government. People know this, therefore, we will thrive to reform the Election Commission once voted to power," he added.
